Can this controller input accept 24 v , 36 v, 48 v from solar array to charge a 12 v battery bank
34726
Yes, it can. You may use any array voltage up to 150 volts, but be aware that solar panel voltages rise dramatically as temperatures fall. Check the temp. correction factor of the panels that you want to use. Basically don't go over a 90 volt series stack of panels to provide a buffer for when the panels are unloaded and to account for that surprise freezing morning. Over voltage is the surest killer of charge controllers, also be aware that the unit is rated 30 amps output to the battery, not 30 amps in from the panels. David Wardle

David Wardle answered your question correctly. If you exceed these limits however the unit will shut down and the battery won't charge. It will not burn up the unit.

Mine has been inputting 24v for a year now, so I can vouch for the 24v. I believe the information with it said that it could. I can't recall the 36v or 48v however.

i have anywhere from 55v's to 65v's coming from my panels. the max is 30 amps. i have 30 amp breakers on my system so i don't go over

I have six 100 watt Renogy panels wired for 24 volts. The meter that came with this controller reads almost 40 volts. It varies from 30-40 volts depending on battery state of charge (I am using six deep cycle batteries...12v). It works great. Additionally, I have pulled 34 amps down from the high sun which equates to around 815 watts. My unit has NEVER shut itself off. When the batteries are fully charged it will still provide power to your accessories. I am using an DC-AC inverter...so, it really doesn't matter.

I currently have my 12v panels hookeo up in series and inputting 61v to the charge controller. Max DC voltage input from your srray cannot exceed 150v. So, yes, any combination as long as you don't exceed 150v from your array. It will input to your bttery bank at 12v ( or 24v your choice) automatic internal sensing, no manual switching necessary.
34732
yes it can input up to 105 volts and convert it down to 12 volt output automatically .

Can I use this on a 46V load to charge controller to convert it to 12v batteries? Just brought the 36v max(24v) to 12V but think it quickly stop because the higher volts?

The whole point of this type of controller is to take your solar power of any voltage up to 48 volts (in this case) and output the proper voltage 12 or 24 volts to your batteries. Your panels do not need to be 12 volts, they simply need to fit in the specs of the controller which is a 48volt maximum input voltage. It will then regulate your output voltage to 12 or 24 volts, whichever you choose.

Yes as long as you don't exceed the controllers maximum current output. This unit at 12vdc draws 560milliamps

You can use this controller for 12v but there will be power clipping. The best controller would be the Outback FM-80 for 1KW solar panels charging a 12v battery bank.Thanks, ML SOLAR

Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine. The limiting factor that may cause the confusion is that the maximum output is 240watts (12V @ 20amps) if you are connected to 12V batteries. In my case, I was connected to a 24V battery bank and was dumping about 17amps at 26volts into the batteries when I had all panels connected (the 240W + 2x130w). For the money the controller works well. If you connect to 12V battery; 240w is maximum; if you connect to 24v battery you can get 480w.

Did you mean the *250 W panel? If this is the case, then yes this panel is rated for 12 or 24v. However, in order to charge 12V systems you would need a controller that is suitable to charge enough power at 12v. For example, if you are inquiring about our 30A PWN, then the rated specs mention that at 12v is 360W so technically you would be able to use this panel with this charge controller. Be mindful, however, of the fact that PWN step down voltage while MPPT models utilize virtually all the power initially started by the panels.

Unfortunately, this controller is only suitable for 12v and 24v system configurations. 48v would blow out the controller.

I'm a little unsure of your question but by "these" if you mean controllers, I would assume you have solar panels exceeding the 40 amp capacity of a single controller. I think you could connect any number of them you wanted to in parallel each controlling its own set of solar panels. At some point I suppose you could reach the limit of your battery bank's ability to accept any more current though.
1476805
Yes, you can connect directly to a 12 volt battery. No charge controller is needed.

i used 12 gauge from the solar panels to the controller and from the controller to the batteries i used no 6 awg i already had here The no 6 is probably overkill i wouldnt go any less than 8 from the controller to the batteries what is your battery bank at least 24v i hope

only if you use a 12v charge controller and have you batteries wired in series. the output of the panel under load is a bit over 24v.

I have had four one hundred watt panels hooked up to this same charge controller for nearly a year and it works fine. At first, I had them hooked up with the panels at 12v and the battery bank at 12v, then I switched the hookup to two sets of two panels in series to put the panels at 24v with the battery bank remaining at 12v. I get a little more power out of the panels this way because a lower amperage means a smaller voltage drop between the panels and charge controller, even though the wattage from the panels is the same. It works fine. With an MPPT controller, the voltage of the panels is not dumped directly into the batteries so you can hook it up either way. If you hook the panels in sets to reach 24v, then your only limit is the 30 amps to the battery bank. Anything above that is simply lost.
1523595
Yes it will work. I'm using two 100 watt panels wired in series to get 24 volts running to the charge controller and then to my 12 volt battery bank. works great. You'll have have less resistance from the panel to the controller in 24 volts as well.

This unit will definitely provide 24 VDC from a 12 VDC input. I have used several in an application where we needed a 24 VDC supply off of a 12 VDC heavy equipment battery pack. However, charging a battery is typically a more complicated issue - amperage load and not over-charging etc. So you should be good for 24 VDC but I do not know enough in regard to battery charging to say yes or no

The short answer is that while these panels operate at around ~28 volts, they will have no problems powering a 12V system with the right charge controller. The days of matching your panels nominal voltage to your battery bank were obsoleted by MPPT charge controllers. To use an oversimplified summary- an MPPT controller takes whatever voltage and amps coming in from your panels and converts it to whatever voltage and amps your battery bank needs. (Worth noting "however," the closer your battery bank nominal voltage is to your panels the more efficient it will be). The significant price difference you will see on MPPT controllers is due to efficiency differences in this conversion, intelligence on charging the batteries, reliability, etc. MPPT controllers are very affordable and significantly increase efficiency to the point that outside of unique circumstances it's bordering on irrational to consider older PWC technology charge controllers that require you to match the panel voltage to your battery bank's nominal voltage (i.e., 12V panels to 12V batteries). A better question for you to ask and research yourself is "what is the best charge controller for these panels powering a 12V battery bank." Hopefully this helps. Good luck!
